EGGS- laying
(2025: ?; 2024: the pair moved on)
Darius Anderwald:
Komórka jajowa od zapłodnienia musi przejść proces otoczenia białkiem i pokrycia się skorupką. Proces ten przebiega u bocianów czarnych 2 dni.
Once a black stork’s egg is fertilized, it needs about two days to form its protective layers — first the protein coating, and then the shell itself.

CHICKs - hatching
Darius Anderwald:
Średni czas wysiadywania od złożenia przez samicę 1-go jaja do wyklucia się 1-go pisklęcia to 35 dni
On average, it takes about 35 days from the laying of the first egg until the first black stork chick hatches.

Klucia pierwszego bocianka możemy spodziewać się około 14 maja (09.04 + 35 dni inkubacji = 14.05).
We can expect the first storklet to hatch around May 14nd (09.04 + 35 days of incubation = 14.05).

Short history of previous seasons

NEST HISTORY

Season 2025 viewtopic.php?f=160&t=280&p=41231#p41231
description: n 2025, four chicks were raised, which were startled by a human on July 29th. Only one fledgling returned to the nest.

Season 2024 viewtopic.php?f=119&t=192
description: Probably the appearance of a new dominant male caused the pair that had occupied it for the last 5 days and nights to leave the nest. We don't know what happened off camera or whether the birds fought. However, there are differences in the appearance and behaviour of this individual, who appeared here only a few hours after the disappearance of Notek and Nutka.

Season 2023 viewtopic.php?p=11287#p11287
description: A new pair was formed and started breeding with a month's delay. Four chicks appeared in the nest. About three weeks apart, all of them were kidnapped by a hawk: the first one on the 20th day of life, the last "Okruszek" on the 36th day of life.

Season 2022 viewtopic.php?f=76&t=112
description: the nest was occupied and defended by at least one male throughout the whole season from March to August

NEST

This site of black storks on an oak tree in the Sieraków Forest District has been occupied by birds for over 2X years!

For the safety of breeding grounds, the old dry oak was supported by KOO members in 2020 with a special support.
In January 2022, during hurricane winds, an oak tree with a stork nest fell over, so KOO members made an artificial nest on a neighbouring healthy oak tree, exactly at the same height as the previous one. Since stork nests are large and weigh up to half a ton, we used steel supports and a basket filled with natural material from the old nest.
The new nest is moved 5 m away and next to the trunk of another tree.

Pierwsze bociany czarne już w Polsce! Dziś do Sierakowa wrócił Notek. Dziękujemy KOO za pracę w ten weekend. Już niedługo przekaz online z nowym kadrem (fot. D.A.)

The first black storks have already arrived in Poland! Notek returned to Sieraków today. Thanks to the #KOO for their work this weekend. The online stream will be back soon with a new camera angle (photo: D.A.)

Great, applause for our tireless team Darek, Darek, Ewa, Kukasz, Stefan

The male stork (we are not sure if it is the same individual) has arrived at this nest over the last 5 years as follows:
26.03.2022, 22.03.2023, 20.03.2024. In 2025, the stream started very late (23.06); however, according to information from an ornithologist, two storks were observed on the nest as early as 13.04.

In my opinion, the current visitor to the nest is a transient bird (migrant). In the world of black storks, appearing two weeks earlier than the five-year average (2022–2024) is a significant anomaly. It is far more likely that this is an individual seeking a safe place to rest (a so-called 'pit stop') rather than our regular resident, Notek. We are patiently waiting to see how the situation develops.

Samiec bociana (nie mamy pewności, czy to ten sam osobnik) przylatywał do tego gniazda w ciągu ostatnich 5 lat w następujących terminach:
26.03.2022, 22.03.2023, 20.03.2024. W 2025 roku transmisja ruszyła bardzo późno (23.06), ale według informacji od ornitologa, dwa bociany były widziane na gnieździe już 13.04.

Moim zdaniem obecny gość na gnieździe to ptak przelotny (migrant). W świecie bocianów czarnych pojawienie się o dwa tygodnie wcześniej niż średnia z ostatnich 5 lat (2022-2024) to znacząca anomalia. Bardziej prawdopodobne, że to osobnik szukający bezpiecznego miejsca na odpoczynek (tzw. pit stop), a nie nasz stały rezydent Notek. Cierpliwie czekamy na dalszy rozwój wydarzeń.

Państwo Notek i Nutka w Sierakowie już także na stanowisku. Wiosną #KOO dał nową kamerę i 300 mb nowej skrętki. Niestety nadal jest problem, bo cała linia ma ca 750 metrów i trzeba wstawić jeszcze kolejne 300 mb nowej skrętki. Ale ornitolodzy walczą z tematem i z brakiem $. Zdjęcie pary bocianów metodą digiskopingu z odległości ponad 200 metrów (fot. D. Kujawa).

Notek and Nutka in Sieraków are also back at their nest. In the spring, the KOO installed a new camera and 300 meters of new cable. Unfortunately, there is still a problem because the whole line is about 750 meters long. We need another 300 meters of new cable. The ornithologists are working on it, but they are short on funds ($). This photo of the stork pair was taken using digiscoping from a distance of over 200 meters (photo by D. Kujawa)
